Which risk increases when satellite antennas experience sustained, high-intensity solar radiation?

💡 Explanation

Solar radiation's thermal effects cause increased thermal noise, thereby reducing impedance matching efficiency. This occurs specifically because differential expansion changes the antenna's geometry. Rather than improving SNR, antenna performance degrades; therefore mismatched impedance occurs, resulting in high signal reflections.
